Vivaciti Surfwise speed.

Has anyone noticed when downloading a large file say a 200 mb test file with multiple threads from TBB, outside office hours that it starts off full speed for 5 seconds then seems to reduce for the rest of the download.

eg at 20:45 I did a couple of tests on Win8 and XP with the TBB test file and the above was observed, started off on meter 16.4 mbit/s then after 5 seconds dropped to 11.6 mbit/s for the rest of the 200 mb download. Throttling or QoS kicking in? Anyone else confirm? My line used to max out for the full download.

It could be to do with buffering within your IS system.

What is IS system and why did it just start doing it?

I have the same package as you. I have raised a ticket with Vivaciti and sent them tracert / ping stats at the times I have been affected the most. That leads me to ask, is there a certain time this happens?

I seem to have problems after 17:00hrs.

My pings have settled down now but speeds are [censored].

I'm not sure I have only just noticed it tonight at 20:45 I will have to do more testing, but speedtesters are no good for this problem only large files from decent servers and then again speed doesn't reduce much. More testing needed.

IS = Internet Security, basically anti-virus and firewall.

These could be the issue if their buffer fills up at the start because they can't vet the stream as quickly as it arrives. Once the buffer is full, the stream has to stop and start as they pass stuff on out of the buffers.

Ahh now I understand. Have kind of ruled out OS and IS because have tested on a dual boot system with XP and Win 8. XP has Nod32 and win 8 is using Defender.

Heres a screenshot showing the initial fast download of XP SP3 network file 316mb

Only things that are common are router, NIC and line. Nothing major I still get files reasonably fast but something has changed as I used to get a flat line when downloading from good servers.

Edit: Thought I had cracked it, Sugarsync was uploading so thought I was saturating the upload so quit Sugarsync but still the same. Have opened a ticket with Vivaciti.

Here's a trace to TBB but with routers nowadays not prioritising pings I dont know how useful it is.

It does now beg the question, do we need some other form of test to ensure that we have a valid connection. I have no idea what that could be.

Does this only happen when downloading from this site? or does it happen with others too?

I had a program called TCP Ping which was useful, will have to search my archive.

All large download files, be it from here or Microsoft or the download test files cloud based in England. Slightly different meter pattern during office hours, seems to vary from 11.6 to 16.4 mbits in equal measure. Ticket has been forwarded to Vivaciti NOC.

Well I have resumed testing with Jdast and extended the download test time to 15 seconds with multiple threads. So far the symptoms are the same, first 5 seconds full speed then starts reducing and getting a bit wobbly for the remaining 10 seconds giving an average download of 15 mbits. If I leave Jdast at its default settings of 5 second test I get 16.4 mbit average.

Have ticket open and waiting for NOC to get back to Vivaciti to try and explain.

Be interested in seeing how you fare with the new tester

Similar results.

The single thread tends to be all over the place but the x6 maxes out then starts to wobble and go downward. This seems to be irrespective of server as Jdast does multiple threads from multiple servers at once. First few seconds maxes out then starts wobbling about.

Another test for reference, similar graph both single and multiple thread with d/l stopping at one stage on single thread.

I've seen graphs like that when I forget test is running and refresh a web page

Mine just wobbles at the end:

Well Karl called me on Monday but we were both scratching heads as to what could cause this. Have left it with him and done a few tests but it used to be with the same setup I could download at just under 2 megabytes/s, now it's more like 1.5 mB/s.

Have adjusted my Billion router to 6db the default line SNR and performed a few tests, no different unfortunately. Just received a ticket update from Vivaciti saying they were waiting for this info but I updated the ticket with these tests on the 25th. I wonder if they are not receiving ticket updates or something, anyway have put it here for Karl/Vivciti to see.

Well something has changed I am now able to download at 1.7 mB/s on a 200mb file at 6db.

This is now fixed, getting a solid 16.4 mbit download on Windows XP SP3 for Networks file. Daisy must have increased the capacity somewhere as my line is now maxing out for the whole 300 mb file as of two days ago.

Banger,

Hope your keeping well.

I have noticed a difference over the last 10 days also. Pings are back down to 14ms which is great, but gaming is a total mess. I ran Trace cert that shows a problem with Daisy (te0-1-0-0.cr02.ts1.bb.daisyplc.net [62.72.137.122]) seems to be the problem.

I have found this post by TiMeTraVeLeR on thinkbroadband who is also having a problems.

Have you seen this problem when completing a tracert?

Hi,
The hop you have reported in the thread is not showing any issue, routers are not set to respond to an ICMP packet if they have something better to do and the fact that the following hops are all OK shows this is not the issue.
Have you raised a ticket as yet? Also it may be helpful to run a trace to the gaming servers you seem to be having an issue with.

Well its been a few days since my last post and I'm really happy with the speed I'm getting now, dunno what Daisy has done, but keep it up. Rock solid max speeds my line can take.
